electronic product testing refers to the process of checking whether the quality of electronic products meets the relevant standards and requirements by conducting various methods of testing, inspection and verification. electronic product testing is an important bad section to ensure the quality and safety of electronic products. common electronic product testing items include the following problems:
safety regulations detection insulation resistance: all household appliances must have sufficient housing and internal component insulation resistance to prevent electric shock accidents.
overload protection: electrical appliances must have overload protection function, when the electrical overload can automatically power off, to avoid fire and other accidents caused by overload.
grounding protection: all household appliances must have grounding protection function to ensure that the electrical shell can be effectively grounded to avoid electric shock accidents caused by leakage.
insulation material: the material used inside the electrical appliance must have sufficient insulation performance to prevent the danger caused by short circuit or electricity leakage.
safety signs: all household appliances must be equipped with clearly visible safety signs to remind users of the correct use and maintenance.
electrical lightning protection: some household appliances must have lightning protection function to ensure that they can work normally in thunderstorm weather and not be affected by lightning.
waterproof and moisture-proof: for the electrical appliances that can potentially contact with water, it must have the waterproof and moisture-proof function to ensure that the short circuit or leakage will not occur in a wet environment.
emc testing: the ability of the equipment or system to operate in its electromagnetic environment does not produce intolerable electromagnetic interference with any equipment in its environment. therefore, emc includes two requirements: on the one hand, the electromagnetic interference generated by the equipment to the environment during the normal operation cannot exceed a certain limit; on the other hand, the appliance has a certain degree of resistance to the electromagnetic interference existing in the environment of the equipment, that is, electromagnetic sensitivity.
electronic reliability detection: whether the ability of the electrical products to complete the specified functions under the specified conditions and within the specified time (for the frequent operating electrical products) meets the standard requirements
environmental adaptability detection :the product can achieve all the predetermined performance and functions under the action of the comprehensive environmental factors in the service process and will not be destroyed, which is the concrete embodiment of the product's ability to adapt to the environment, is an important quality characteristic, and whether it meets the standard requirements
performance detection: different electronic products have different functions and performance, to verify whether they meet the customer's requirements.
the purpose of electronic product testing is to ensure that the quality of electronic products meets the relevant standards, can operate normally, and at the same time can avoid safety accidents and other problems in the process of use. any electronic product needs to be strictly tested before leaving the factory
